Is it ok to copy a W5 head and make it better or are we just mad at Speedmaster

The problem was Speedmaster basically took some of this particular manufaturer's existing stock of parts, crossed his name off it and put theirs on it. It's one thing to take a bare, generic casting that's available to anyone and put your own name on it but using existing inventory produced by someone else with their name already on it, crossing it out and slapping your own name on it to sell for your profit is the issue.

Is this what happened? I thought I read the part was marked "Broader Performance" or the equivalent trademark on it.
